You are looking for CPA affiliate networks. There are over 125 of these type of networks listed in my signature. These are the sort of networks that have all these type of zip and email offers where the visitor to your site doesn't even have to use a credit card for you to get paid with many of the offers in most and if not all the networks.
There are many CPA networks offering a lot of campaigns of this type. Before starting using them, ask your AM about conversion rates and suggestions to avoid bad tracking.
